My invention comprises novel details ot Similar numerals ot reference indicate improvement that will be more fully hereu corresponding parts in the several views. inatter set forth and then pointed out in' l have illustrated my improved means for 511' the claims. 'feeding'A endsor heads A in conjunction with Reieienc, is to be had to the accompanymechanism tor successively eedingcan bod m5 ingl drawings forming` a part hei-cot, whei'eies B, including' a rotative turret 1., (Figs. 1 iuand 2), to which said ends and bodies are ted Fig. 1 is a side elevation ot a can seaining in proper timing` for locating the ends on the turret over the bodies in a successive manner to permit the ends to be seamed upon the bodies. The turret may be rotated stepby-step in consonance with the feeding of the heads and the can bodies by any suitable means well known in the art.

A suitable elongated frame 2 is attached at one end, as at 3, (Fig. 2), to the frame or casting 4 which supports the turret and its operating mechanism. The outer portion of frame 2 is supported and braced by a rod 5 shown pivotally attached at 6, (Fig. 5), to the outer portion of frame 2, said rod being pivotally attached at 7 toa support 8 on frame 4, which may be adjusted by a screw S, (Fig. 1). A feeder for the can-ends A is shown in the form of an endless chain 9 which Vpasses at its forward or delivery end over a sprocket wheel 10 carried by a shaft 11 ournaled between the side bars at the inner end of frame 2', said chain at its opposite end passing over a sprocket 12 carried by shaft 13 journaled upon frame 2 at its outer end, (Figs. 4, 10, 16 and 17). The feeder chain 9 is provided with a series of spaced stops or projections 14 shown in hook-like form, (Fig. 10), adapted to engage and push the can-ends A. At the sides of feeder chain 9 frame 2 is provided with spaced guides or ledges 15 for guiding the side edges of the ends' A, (Fig. 2), which ends slide upon a longitudinally disposed way 16 that is shown provided with a longitudinal groove 17 through which the upper run of the chain 9 slides and by which it is supported, (Fig. 11). The feeder chain 9 is operated stepby-step to feed can ends A successively to the receivers 1a of turret 1 upon supporting means or ledges 1b'of the receivers. Loosely mounted on shaft 13 are spaced spur gears 13 in mesh with corresponding racks 19 that extend from a. plate or bar 20 that is guided to reciprocate along guide rails 21 secured to frame 2., (Figs. 10 and 11). The gears 18 are provided with projecting arms 22 that pivotally support dogs 23 by means of studs 24, (Figs. 1.6-19), which dogs are adapted to engage notched disks 25 secured upon shaft Then the racks 19 move toward the left in Fig. 17, the dogs 23 will engage the disks 25 to rotate shaft 13 to cause sprocket 12 to advance the feeder chain 9 a step to feed an end A to the turret, andv when said racks more in the opposite direction the dogs 23 will be moved reversely to again engage disks for another forward movement of the feeder chain, and so on step-by-step for each end A to be fed. Since can-ends or heads A may vary in length I prefer to provide the feeder disks each in two members 25 and 25 secured together by rivets 25', (Fig. 18), the disks of each pair having notches 125C, Q5 respectively unequally spaced, (Fig. 17), say three of such notches on disk 25 and two of such notches on disk 25h. `When the dogs 23 are placed as shown in Fig. 16 they will engage the outer disks 25a to actuate the feeder chain forv one extent of feed for each step, and when it is desired to cause the feeder chain to operate for a different length feed the position of the dogs is reversed on the respective arms so that the dogs will engage the disks 25h. A detachable protecting cover is shown at 26 enclosing the gearing, dogs and racks described over a shield 27 carried at the outer end of frame 2.

Vfhile l have shown two racks 19 and corresponding dogs 23 and disks 25, it will be understool that they are used in duplicateto balance the operation of the feeder chain, but if desired one set of corresponding dcvices may be used for the purpose.

Means for operating the feeder chain 9 are arranged as follows z-From the forward end of plate 20 a pin 2S depends, (Figs. 10, 11 and 13). The pin 28 is shown provided with a head 28 secured to plate 2O by screws 29, (Fig. 11), said head having an opening through it at 23" through which the lower run of feeder chain 9 passes and rests upon a guide bar 3G that is located within opening 28D. Said guide bar is carried by a sub-frame 31 secured within frame 2 below the feeder chain, (Figs. 10, 11, 13 and l14). The frame 31 is shown supported upon frame 2 by screws 32, (Fig. 11). The pin 28 is moved in one direction, (to the right in Fig. 10), by means of a slidable member 33 adapted to push said pin, which member is guided to slide upon spaced guide rails 34 that are shown supported by the bar by means of bolts 35 passing through the bar 3() and rails 34, (Figs. 10 and 14). The pin 28 is adapt-ed to travel back and forth between the guide rails 34, (Fig. 11). .the slldable member 33 1s provided with a depending projection or pin 36 shown secured to member 33 b a screw 37, said projection having shoulders at 38 bearing against the lower edges of rails 34. (Fig. 15). A link 39 is pivotally attached to the projection 36 by means of pin 40 which also retains a sleeve 41 on said projection. Link 39 is pivotally connected with a crank rm 42carried by shaft v43 journaled upon bracket 44 supported by frame 2. A crank arm 45 on shaft 43 is pivotally connected with a pitman 46 that is pivotally connected with a crank pin 47 carried by a sprocket wheel 4S driven by a chain 49 that may be driven by a sprocket wheel operated by any desired power transmitting part of the ma chine, such as by shaft 69, (Fig. 20), whereby when the pit-man 46 is operated the member 33 will be reciprocated, (Fig. 1). A feeding-hook is adapted to engage pin 9.3, (Fig. 14), and is pivotally carried by projection 36, the lateral arm 50a of the feeding hook being shown vresting upon sleeve 41, beneath enlargement 38a of projeclil) tion 38, whereby the hook is. supported to rock, (Fig. 15). The hook 50 has a forward beveled edge 501 adapted to engage a rockable finger 51 designed to move the hook laterally to prevent it from engaging the pin 28 when a cam body B is not fed to receive an end or head A, whereby to prevent feeding movement of feeder chain 9. The finger 51 is normally out of the'path of the hook 50, or depressed, as indicated in Figs. 10 and 13, and the feeding hook is normally retained in position to engage pin 28, in the position shown in Figs. 6 and 14, by means of spring 52 shown attached to pin 53 on slide member 38 and to pin 54 on the hook, (Figs. 13 and 14). llVhen can bodies are being fed successively to the turret the nger 51 will be retained depressed out of the path of hook 50, (Fig. 13). l/Vhen a can body does not pass in its proper order of succession to the turret the linger 51 will rise into the path of hook so that the beveled edge 5()b of the hook will approach and engage finger 51, (Figs. G and 7), near the limit of the corresponding stroke of slide member 38, whereby the hook 50 will be moved to one side from operative position with relation to pin 28, (Fig. 8), to be retained from engagement with said pin on the next forward stroke of member 33 to the left in Fig. 8, so as not to pull pin 2S and thereby not operate feeder chain 9, since finger 51 extends along one side of pin 28 so that the tip end of the hook will slide past said pin on the stroke to the left in Fig. 8, leaving the racks 19 and chain 9 unoperated during the absence of a can body in the appropriate position. The linger 51 is secured upon a rock shaft 55 journaled upon bracket 44, (Figs. 1, 5 and 13). Shaft 55 is provided with a crank arm 56 connected by link 57 with crank arm 58 secured upon a vertical shaft 59 journaled upon bracket arm 44a and shaft 59 has a crank arm 60 connected by link 61 with bell crank lever 62 that is pivotally supported at 63 upon frame 64 of the can body feeding mechanism, (Figs. 1 and 2).

'ihe frame 64 extends outwardly from the frame or casting 4 at an angle to frame 2 and is provided at its outer end with a standard 65 so that the can bodies may be fed to the can feeding' mechanism. The can-body feeding means illustrated comprises an endw less belt or conveyor 66 shown mounted upon roller 67, 68, 69, (Fig. 1), journaled upon the frame. jin idle pulley7 70 carried upon a lever 71 journaled upon the main frame and operated by spring 72 serves to maintain desired tension in conveyor belt 66, (Figs. 1 and 20). At the sides of belt 66 are located spaced walls 73 extending above the belt, supported by frame 64, whereby the containers or can bodies B are guided. Said conveyor belt may be driven continuously in any desired way. A driving shaft 74 has a gear 75 in mesh with gear 76 secured on shaft 77 journaled in suitable bearings on the main frame, which shaft is provided with gear 78 in mesh with gear 79 on shaft 67 of roller 67, whereby the conveyor belt may be driven continuously. The open end can bodies l5 may be delivered to the conveyor to lie horizontally thereon by any suitable means, or manually. The conveyor is adapted to feed the can bodies to a transferrer 8O rotatively carried by shaft 8l journaled in suitable bearings on the frame. rlhe transferrer is adapted to rotate to successively raise the can bodies delivered there to from a horizontal to an upright position, so that the open ends will be elevated into a position to receive the ends or heads A to be seamed to the body. The transferrer may be of any desired construction and is shown comprising spaced lingers 8Oa having curved projections 80h adapted to operate in spaced slots 82 in a plate 83 secured upon the main frame in substantial alignment with the upper run of conveyor 66 to receive the can bodies therefrom, (Figs. 20 and 2l 'lhe transferrer is shown provided with stops 80c to ol'Jstructl the can bodies they are advanced to the transferrer by the conveyor, (Fig. 20). In the body receiving position the transferrer is located as indicated in Fig. 20, with its arms 80" substantially within the slots 82 of plate 83 and the lingers 801 below. llVhen the transferrer is rotated to turn the can body to a vertical position, with its open end uppermost, the lingers S()b will obstruct the advance of can bodies to the conveyor until said fingers are again lowered, (see the dotted position of the transferrer in Fig. 20).

In the example illustrated the transferrer 8O is rotated back and forth for the purpos'.- of alternately receiving the can bodies and turning them upwardly. For suoli purpose l have shown shaft 81 provided with a gear 84 in mesh with a rack 85 that is pivotally connected at 86 with a reciprocative rod 6i' that is operated by a cam 88 secured on ehr t 67, (Figs. 2 and By prefer-ence, rod if.' is provided with resilient `means to actuae the rack 85, for which purpose said rod is shown made in two parts 87a and 87, (Fig. 3), having relative movement and provided with an interposed spring 89, shown coiled around rod part 87 and slidable in a bushing` 90 carried by a cylinder 91 containing said spring, the rod part 87"l having a piston-like head or stop 92 between which head or stop and the bushing 99 the spring 89 is located. The rod part 87h shown secured by a nut or head 93 to cylinder 91. Air in cylinder 91 between heads 92 and 93 aids rod part 87b in pushing rod part 87a to actuate the rack in one direction, the spring 89 actuating the rack in the other direction.V A

port 911 in cylinder 91 permits flow of air into and from the cylinder. A spring shown coiled around rod part 87, bears against bushing 90 and against bearing 96 for moving rod part S7, (Fig. 3). The rod part S7b is shown provided with a slotteav head 97 slidable on shaft 67u and provided with a projection 9S operative in the cani groove S8 of cam 88, (Fig. 3). lVhen said cam is rotated the rack S will be reciprocated to rot-ate transferrer S0 back and forth, the springs S9 and 95 resiliently resisting operation or' the rack by camL 88 so that the transferrer will not injure the can bodies. lllhen the transferrer is rotated to raise a can body to a vertical position the latter is brought to rest at its side against a wall or stop 99, (Fig. 20). Said wall or stop may be adjusted with respect to the transferrer by means of slots 99a in the base of the wall and screws 100 shown passing through said slots and secured to the main frame, (ltigs. 2 and 21).

Vfhen a can body is presented on end with its open end upwardly disposed it will be in position to be transferred to a receiver 1"L of the turret 1. The turret is carried by a shaft 101 journaled in the main frame 4, which turret may be rotated step-by-step by any well known mechanism utilized in can seaming machines, The receivers or pockets 1a of the turret are shown radially disposed below the ledges 1b and have their outer sides open to receive the can bodies which rest on the plate 83, beneath can ends supported by the ledges 1b, (Fig. 20). `Meins are provided to push the can bodies from the transferrer into the turret. ln the example illustrated a pusher or plunger 102, 2), is located in register with a pocket 1a of the turret and is shown comprising a suitable head upon a reciprocating rod 103 guided by bearing eL supported by the frame, the rod being adapted to be reciprocated to push the can bodies from the transferrer to the pockets of the turret. Any suitable means may be provided for reciprocating the pusher or plunger 102. A forked arm 105V pivotally supported on shaft 106 journaled in bearings in the main frame receives lateral projections 107 extending from rod 103, 1). The shaft 106 is shown provided with a crank-arm 108 pivotally connected with block 109 slidable on a rod 110. The rod 110 has a stop 111 against which a spring 112 bears, said spring also bearing against block 109, the latter being retained on the rod by a nut, whereby said rod may resiliently push the block to operate the pusher or plunger 103. The rod 110 is pivotally connected with a crankearm 113, (Figs. 2 and 20), pivotally supported at 114 on the main frame, which crank-arm is provided with a projection 115 cooperative with a cam 116 on shaft`f77. Said cam is timed to cause operation of pusher or plunger 103 through the connecting parts described, so that when a can body has been presented by transferrer 80 in position to register with pocket 1a of turret 1, said pusher will push the can body into the receiver and will recede from the transferrer, which will operate to receive another can body and present it in register with a receiver of the turret just after the pusher has been retracted from relation to the transferrer, and so on.

lVhen the machine is in operation the can bodies B are fed successively to the transferrer by the conveyor or belt 66, and the ends or heads A are fed correspondingly and successively to the ledges 1b of: the turret, in timed relation one to another, the turret being rotated step-bystep for each can body and head to be seamed. The arrangement is such that each time that the turret comes to rest an end or head A will be presented into a receiver of the turret, the receivers being provided with open supporting ledges at 1b at the upper parts of the receivers beneath the ends A, for the ends A, so that the flanges A of the ends A may rest on the ledges to expose said ends to the bodies B that are pushed by plunger 102 from the transferrer S0 into position in the receivers, which bodies rest on the table C beneath the turret receiv-ers so as to be slid around by the turret. At 117 is a guide curved around along the exterior of and spaced from the turret in position to engage the outer end of the ends A when the latter are deposited upon the ledges 1b of the turret receivers, (F ig. 2), from which the ends A project when fed by the feeder chain 9. The guide 117 is eccentrically disposed or cani-like with respect to the axis of the turret, with the end of the guidek that is near the feeder chain 9 farther from the turret than its opposite end, so that as the turret rotates the ends A carried thereby, (that are not pushed inwardly in the receivers to the limit by chain 9) will, bythe guide 117, be slid along the ledges 1" to the proper inward position therein as the turret rotates. Guides 118 are located outside of the turret beyond the guide 117 to keep the ends or heads Ain position in the turret until they are brought to rest with the can bodies therebeneath at the point D, (Fig. 2), where the bodies and ends are seamed together. Each time that a can body is deposited in the transferrer 80 the latter will rock to tilt the body from a horizontal position to a' vertical position with an open end extending upwardly, (Fig. whereupon plunger 102 will operate to push the body into a receiver of the stationary turret beneath an end A that has been delivered tothe corresponding end supporting means or ledge 1b of the turret. The transferrer will then be moved into position to receive another body B and after the turret rotates a step another end A will be brought to rest in position to be above such body B that is to be pushed by plunger 102 into the corresponding receiver of the turret, and so on successively.

The turret operates step-by-step regardless of whether a can body has been presented in a receiver' or not, and it is an object of my invention that an end A should not be fed into a receiver of the turret in the event that an appropriate can body should not pass in the proper position for such end A, for which purpose the feeder chain 9 will be stopped from its feeding movement so as not to feed an end A ,in the absence of a body to correspond with such end A. To cause the feeder chain 9 to stop at the proper time the arm 62?L of the bell crank lever G2, (Fig. 2), is located in position to pass through an opening at 11.9 in the corresponding wall 7 3. Said arm will be operated by the bodies B when passing the arm, said arm 62a being shown provided with a roller 621 to engage the can bodies. When the can bodies engage the roller 62b the bell crank G2 will be operated to cause the linger 51 to be depressed out of the path of hook 50, so that said hook during its movement to the left in Fig. 10, may pull pin 28 to operate the feeder chain 9 a step, and on the return stroke the slide 33 will operate said pin to push the racks 19 reversely ready for the next feeding step, and so on. If a can body does not pass roller 62b the arm o2u will be moved by spring 120 to cause said arm to pass through wall 7 3, whereupon the .finger 51 will be raised to the position sh own in Fig. 7, so that when hook 50 engages said linger on the return stroke said hook will be disengaged from pin 28, (Fig. 8), and will not engage said pin on the next forward stroke of the hook, so that the racks 19 will not be moved and the feeder chain will remain at rest. When a can body next operates arm 62a the latter will cause the 'linger 51 to descend from the path of the hook 50 so that the latter on its next stroke toward pin 28 may engage the same and snap behind it, to the position shown in Figsy and 14, ready to operate the feeder chain 9 to feed an end A to a receiver of the turret corresponding to the last named can body. The pin 63 that pivotally supports crank arm 62 is shown carried upon an adjustable arm 63a having slot @3b receiving screws 63C carried by frame 611, whereby the position of the bell crank 62 may be adiusted according to the character of the bodies A to be fed, (Fig. 2). By not feeding an end A to the turret in the absence of a corresponding can body danger that seaming tools would engage such an end A without a corresponding body is avoided, hence dillicul ties heretofore experienced in feeding can ends or heads in the absence of a body, or feeding bodies in the absence of an end or head, are avoided.

Any appropriate or well known searning tools may be provided for seaming the flange of the bodies and their ends A together. Spaced seaming rolls 121 are supported over a suitable part of the turret, indicated in dotted lines in Fig. 2, and driven by inten meshing gears 122 carried by shafts 123, 124e, (Fig. 22), which parts may be supported and rotated in any desired manner to cause the seaming rolls to act upon the edges of the end A and the can body to seam them together in a well known way, such as indicated in Figs. 1, 1b.

Any suitable means may be provided for elevatingthe can bodies with their closures or ends A thereon to the seaming tools, such as by means of a reciprocative lifter indicated at 125 adapted to be operated by a reciprocative rod 126, (see dotted lines in Fig. 20), to be actuated in any suitable or well known way to raise and lower the can bodies when the turret comes to rest.` rlhe seaming devices' and lifter which form part of thel seaming mechanism, will be caused to operate in timed relation to the step-bystep movements of the turret to cause seaming the ends A to the can bodies at each stop of the turret.

After the closures or ends A have been seamed to the can bodies the latter may be ejected from the turret by any suitable or well known means or manually, and may be..received on a conveyor' to carry them away, or may be delivered in any other suitable manner. At the delivery point a wall 127 obstructs the seamed can bodies, (Fig. 2), where a suitable conveyor 128, such as a belt, may receive the can bodies to deliver them where desired, or to another seaming machine where such machines are arranged in tandem to first seam an end A to lone end of a can body and thereafter to seam another end at the opposite open end of the can body. The conveyor or belt 128 may be supported similarly to conveyor 66, one end of the conveyor 128 being shown passing over a roller 129 whose shaft 130 supported by bracket 131 is provided with a sprocket wheel 132 receiving chain 133 from drive sprocket 1341 on shaft (i9a of roller 69 operated in consonance by and with the conveyor 66, (Fig. 20). l/Vhen the can bodies are delivered upon the conveyor belt 128 they may be turned on their sides so that the then open ends extend rearwardly and may be fed by said conveyor successively to a second transferrer associated with a second turret, which sealning devices have end feeding mechanism of the character described, which transferrer will operate to turn such can bodies upwardly with the open ends uppermost, and, the previously closed ends downwardly disposed, in position lto be pushed by a corresponding pusher 102 into the associate turret, which mechanism similar to the end feeder mechanism set forth may feed ends in the manner stated to be seamed to the can` bodies in manner before described. Such arrangement enables the continuous operation of containers or can bodies to have the closures or ends applied and seamed at opposite ends Without any manual handling from the tin-e the bodies and ends are placed upon the respective conveyors.

One of the advantages of my invention is that the feeding of the ends A may be accurately determined because the operator may place the endsy A manually upon the feeder chain 9 in position to be fed by the appropriate stops or pushers 14, and as such feeder chain is in plain vien7 of the operator assurance may be had that the ends A Will be on the feeder chain in proper successiv order, and there will be no danger that two superimposed ends A will be simultaneously fed to the turret, and no jamming or crowding of the ends Will take place since the ends A are not fed from a stack of ends and clogging of the machinery or injury thereto from improperly fed ends A is avoided.

In order to apply lubricant to the ends as they are fed by the feeder chain 9 I provide a roller 135 shown having a peripheral groove adapted to correspond to the shape of the ends A, which roller is pivotally supported upon brackets 136 secured upon frame 2, so that the roller may make contact With the surface of the ends. A distributing roller 137 in contact with roller 135 is pivotally carried by brackets 136. The shafts of said rollers are. shown supported in slots in said brackets so thatthe rollers may be readily removed and replaced according` to the shape of the ends A being fed. The rollers 135 and 137 may be supplied Wit-h a suitable lubricant, such as soapy Water, by any suitable means, such as from a sight gage 138 suitably supported over the rollers, as indicated in dotted lines in Fig. 5. The frame 2 is shown provided with downwardly and outwardly disposed passages 2', (Fig. 12), through which the excess lubricant may flow.

The can body feeding devices and the general construction of the turret and the seaming devices form no specific part of my present invention beyond their combination with my improvements, as such parts are substantially the same as set forth in the application of Charles Gueritey, filed November 27, 1922, Serial No. G03, 610, for means for feeding can bodies.

Having now described my invention what l claim is I 1, The combination -of seeming nie- Chanism, a. rotative turret provided with receivers for can bodies and having means to support can ends over the bodies, and means to feed said bodies to said receivers, with means for feeding can ends to said support- Iing means, comprising means to guide ends successively, a feeder' provided with means to push said ends, and means to operate said feeder step-by-step in consonance with the operation of the seaming mechanism.

2. The combination of seaming mechanism, a rotative turret provided with receivers for can bodies and having means to support can ends over the bodies, and means to feed said bodies to said receivers, with means for feeding can ends to said supporting means comprising means to guide ends successively, a feeder provided with means to push said ends, means to operate said feeder step-by-step in consonance with the seaming yand body feeding mechanism, and means operative in the absence of a can body in said body feeding mechanism to stop the operation of the end feeder.

3. The combination of seaming mechanism, a `rotative turret provided With receivers for can bodies and ends, and having means to support can ends over the bodies, and means to feed said bodies to said receivers with an endless feeder for can ends provided with means to push said ends, means to guide said ends to the supporting means, .means to operate said endless feeder in consonance with the sea-ming and body feeding mechanisms, and means operative in the absence of a can body in said body feeding mechanism to stop the operation of the endless feeder.

4. The combination of seaming mechan-ism including a rotative turret provided With receivers for can bodies andy ends, with. an endless feeder for said ends provided with means to push the ends to said receivers, Wheels supporting said feeder, a reciprocative bar provided With a rack, a gear cooperative with said rack, a dog connected with said gear, a toothed disk cooperative with said dog and connected with one of said Wheels, means to reciprocate said bar, a pin extending from the bar, a reciprocative member provided with a hook, said member and hook being cooperative with said pin to reciprocate the bar, and means to cause the hook to release the pin in the absence of a can body corresponding to a can end.

Y 5. The combination of seaming mechanism including a rotative turret provided with receivers for can bodies and ends, with an endless feeder for said ends provided with means to push the ends to said receivers, Wheels supporting said feeder, a reciprocative bar Drovided With a rack, a gear cooperative `with said rack, a dog connected with said gear, a toothed disk coiso operative with said dog and connected with one of said Wheels, means to reciprocate said bar, a pin extending from the bar, a reciprocative member provided with a hook, said member and hook being cooperative with said pin to reciprocate the bar, a finger adapted to cooperate with said hook to release it from said pin, and means normally tending to retain the linger in operative relation to the hook, to cause the hoolr to release the pin in the absence of a can body corresponding to a can end, said means being operative by a can body to move the linger out of operative relation to the hook.

6. rhe combination of seaming mechanism including a rotative turret provided with receivers for can bodies and ends, and means to supply can bodies` successively to the seaming mechanism, with an endless feeder for said ends provided With means to push the ends to said receivers, Wheels supporting said feeder, a reciprocative bar provided With a rack, a gear cooperative with said rack, a dog connected with said gear, a toothed disk cooperative with said dog and connected with one of said Wheels, means to reciprocate said bar, a pin extending from the bar, a reciprocative member provided With a hook, said member and hook being cooperative with said pin to reciprocate the bar, a linger adapted to cooperate with said hook to release it from said pin, and means having a portion normally in the path of bodies in said supply means for aining the linger in operative relation to the hook to release it from the pin in the absence of can bodies, said portion of the last named means being operative to cause said finger to move out of operative relation to the hook when engaged by a can body.

7. The combination of seaming mechanism including a rotative turret provided with receivers for can bodies and ends, With an endless feeder tor said ends arranged to deliver the ends to said receivers, means to operate said feeder step-by-step in consonance with the operation of the turret, and a curved guide adjacent to the turret, said guide having a portion adjacent to the delivery end oi said feeder, another portion of said guide being nearer to the turret than its first named portion to push ends into receivers ot the turret during rotation of the latter.
